What Badd9 is made of

Badd9 (B add9) is built from the notes B, D#, F#, C#, with the interval pattern 1, 3, 5, 9.

Stack 1, 3, 5 and 9 on a root of B and you get B, D#, F# and C#. That interval recipe is what makes the chord an add9 chord — move the same shape to another root and the character travels with it, which is why F♯add9 sounds like a transposed Badd9.

Add 9: Major triad with an added 9th; pop and folk staple.

Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with D♯ rather than its enharmonic equivalent.
